Progress MonoRoll HE-Serie

Energy-efficient production

Sometimes, innovation is a marathon not a sprint. This is certainly true of the Progress MonoRoll HE – a revolutionary pellet mill from PTN (Pelleting Technology Netherlands), part of the Triott Group. Thanks to its unique design developed over many years, the MonoRoll HE requires 20-25% less energy versus traditional pellet mills with the potential to save nearly € 33,000 per year, per pellet mill and achieve ROI in three years*. It’s also more durable and robust, less noisy and easier to operate with hardly any vibration – thus offering improved cost of ownership and excellent ROI for feed mill owners and manufacturers.

The challenge

The traditional pellet mill uses two or three rollers to press the conditioned mash feed into their final (pelletized) form. For many years it would feature three rollers, each set at a 120-degree angle; which evolved to a dual-roller. But neither technology could truly solve the challenge of excessive force on the heavy bearings of the solid main shaft – which in turn made the machine both energy and economically inefficient and even unstable, with heavy noise and vibration. It was in the early 80’s that the founder of PTN, Tony van Benthum, began exploring a single-roll principle. And it’s his son Marty van Benthum, CEO of PTN, who has now brought the project to commercial fruition after picking it up again in 2015.

The solution

After more than three years of intense re-development, PTN’s parent company Triott has now officially launched the Progress MonoRoll HE pellet mill – the only single-roll machine available today, and based on unique technology. “Our decision to revisit this technology was driven purely by what customers in the feed industry were telling us,” says Marty. “The pellet mill is probably the most energy-hungry machine in the entire feed mill; yet manufacturers are under constantly increasing pressure from regulators to reduce their emissions. This technology enables them to achieve this – while increasing their overall price/performance. We believe it’s a real win-win – especially for larger mills running multiple pellet mills.”

The single Monoroll pellet mill is strong, sturdy and virtually silent with minimal vibration and much lower RPM than traditional pellet mills. Furthermore, the wider diameter of the single roller significantly reduces the risk of roll slip common in conventional pellet mills. “The steepness of the inlet angle between the big roller and the die is much less than with a 2 or 3 roller pellet mill,” explains Marty.
